Verdict Suspicious
Is uplay_ r1_ loader64. dll safe? Treat it as suspicious.
This unsigned, heavily protected game-platform loader DLL draws 5 of 75 generic or rule-based detections, with no named malware family and a long, widespread submission history.

Why Suspicious? 5 antivirus engines flag it; nothing else confirms it.
Limited evidence · One sign points to a problem; nothing else confirms it.
Avoid running this unofficial loader; use the official game client and keep your antivirus enabled, and delete the file if you did not intentionally obtain it.
What to do now4 steps
Some signs point to a problem, but nothing confirms it is harmful. Treat it with caution.
What to do
Don't use it unless you're sure where it came from.
Check where you got it: an unexpected attachment, a link someone sent you or a re-upload is a red flag.
If you can't confirm where it came from, delete it. If you need the program, download it again from the publisher's own website.
If you already used it
Stop using it, run a full scan with your antivirus and watch for unexpected behavior or security alerts.

Why we think so
4 points against it and 4 in its favour, checked against the scan evidence.
The reasoning behind this verdict
Five of the 69 antivirus engines that checked it flag this DLL, including one major antivirus engine with a generic trojan label and others with rule or grayware labels. It is unsigned, wrapped in a code-protection layer and looks like a game-platform emulator loader of the kind shipped with cracked games, first seen on Nov 17, 2014.
The detections are generic: TrendMicro-HouseCall reports a generic trojan, CrowdStrike calls it grayware, and DeepInstinct, Malwarebytes and APEX give rule-based verdicts, with no family named. The binary carries high-entropy protected sections, and a community annotation links it to a VMProtect obfuscation rule, which commonly triggers rule-based engines. It has no signature, so no publisher vouches for it. On the benign side, more than 1,100 sources have shared it, no reference database lists it, and the sandbox summary recorded no malicious verdict, no injection target and no network contacts. That mix points to an unofficial game loader whose origin cannot be verified rather than confirmed malware.
What We Detected
5 of the 69 antivirus engines that checked it flagged this DLL. The only major detection is TrendMicro-HouseCall with a generic trojan label; CrowdStrike labels it grayware, and DeepInstinct, Malwarebytes and APEX give rule-based verdicts. No engine names a malware family. The file is unsigned and its code sits in high-entropy protected sections, and a community annotation associates it with a VMProtect obfuscation rule.
Threat Behavior
The sandbox runs loaded the DLL and called exports that imitate a game platform's achievement functions. No injected processes, persistence or network contacts were recorded, and no malicious sandbox verdict exists; no complete host-reputation result is available.
What To Do Now
Files like this usually come with unofficial or cracked game copies, a common route for malware. Use the official game client, keep your security software enabled, and remove the file if you did not knowingly install it.
Where this verdict could be wrong2 caveats
- The file has been shared by over 1,100 sources since 2014 with no malware family named, no malicious sandbox verdict and no reference-database listing, so the detections may be rule-based reactions to its protection layer.
- The exported functions mimic a game platform's achievement API, consistent with an emulator DLL rather than a trojan.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- Shared by more than 1,100 sources since Nov 17, 2014
- No malware family named by any engine
- No listing in MalwareBazaar, YARAify or CIRCL
- No malicious sandbox verdict, injection target or network contact recorded
- Unsigned DLL with no publisher identity
- Flagged by 5 of the 69 antivirus engines that checked it, including one major antivirus engine with a generic trojan label
- Code is hidden in high-entropy protected sections
- Looks like a game-platform emulator loader typically bundled with cracked games

What the test run showed
What the file did on a test computer
Confirmed in the test run
Moderate concern: Contains packed or scrambled code that is harder to inspect (common in installers too).
Moderate concern: Checked whether it was running on a test computer.
Note: Read basic details of the test computer, such as its Windows version.
Sandbox labels we could not confirm (common in safe files too)
Not confirmed: A sandbox rule tagged this run as code injection, but no injected program was recorded.
Not confirmed: A sandbox rule tagged this run as changing how Windows loads code; nothing confirms it.
This file was run on a test computer (a sandbox), not on yours. Labels we could not confirm are listed so you can see them, but they are not treated as evidence against the file.

Signatures and behavior heuristics
Low-severity pattern matches — worth noting but not on their own cause for alarm.
VirusTotal's sandbox summary maps this run to MITRE T1055 (Process Injection), but no injected process of the sample's own was recorded (the analysis VM's own WMI adapter, crash handlers and Chrome updater are not counted). VirusTotal maps T1055 on about half of all files no engine flags, so the mapping alone is not evidence of injection.

Section entropy & packers
No high-entropy executable section or known packer signature was detected. Data and resource sections can still have high entropy without indicating packed code.
How widely this file has been seen
Widely seen in the wild for a long time. High prior this is legitimate; isolated detections on common-old files are usually false positives.
